. hair may be straightened out and which will remain strai htened.

. Another object of the invention is to provide a method of straightening kinky hair which leaves it permanently straight withthat the owner of the hair which is so treated may have a clean head and permanently straight hair.

An apparatus for carrying out this method is shown in the accompanying drawings, in which:

re 1 represents a perspective view -Sl1OW1I1g the use of apparatus for carrying out the method,

Fig. 2 is a similar view showing the hair arranged and held prior to the subjection thereof to steam, and

Fig. 3 is a similar view showing the hair wrapped and in place in the solution carrying flannel prior to insertion in the baking apparatus.

The method constituting this invention consists in first washing and drying the hair to be straightened. The hair is then divided into section about one square inch more or less and placed out straight on the -ferrule 1 of an ordinary waving apparatus, secured to the ferrule in straight out position and held by twine2, which is wrapped around the hair and ferrule and tied as is usual in permanent waving, the hair being saturated with lime sodium carbonate and oil or other suitable liquid and a flannel 3 dipped into ammonia is placed over the hair and tied, as shown at 4;. The protecting tapered tube, not shown, is placed over the flannel and the whole is then put into the electrically heated baker 5. The steam generated from the chemicals while the hair is stretched and tied straight changes the more particuand tinfoil or of either. out the use of any grease, acid or list-erine so air shafts of each strand of hair so that when cooled, the hair will remain straight. It is, of course, understood that any suitable caustic alkali may be used for saturating the flannel since the straightening of curl hair and the curling of straight hair are both dependent upon the treatment by steam con taining alkali while the hair is being stretched. The protecting tube may be made of any suitable material, preferably of paper I claim I 1.
